GENERAL DESCRIPTION
The ML4810 and ML4811 High Frequency PWM Controllers are optimized for use in Switch Mode Power Supply designs running at frequencies to 1MHz. The ML4810/11 contain a unique overload protection circuit which helps to limit stress on the output devices and reliably performs a soft-start reset. These controllers are designed to work in either voltage or current mode and provide for input voltage feed forward.
FEATURES
■ Integrating Soft Start Reset
■ High current (2A peak) dual totem pole outputs
■ Practical operation to 1MHz (fOSC)
■ 5.1V ±2% trimmed bandgap reference
■ Under voltage lockout with 7V hysteresis
■ Soft Start Reset Delay (ML4811)
■ Oscillator synchronization function (ML4811)
■ Soft Start latch ensures full soft start cycle
■ Outputs pull low for undervoltage lockout
■ Accurately controlled oscillator ramp discharge current
■ All timing currents “slaved” to RT for precise control -
